    How hard is the rebuild on this tansmission and transfer case. I am trying to save as much money as possible so I can get everything done to get my blazer back on the road. When I parked it, the tranny and t-case both worked, but were leaking some oil. I want to rebuild them before I swap in my rebuilt 350. No sense in taking it apart twice. Also, on the Hydro conversion, does it matter what year the clutch parts come out of? Does it need to be a second gen, or will 88 and up Fullsize parts work?

    I would just put some seals and new oil in them, if your worried about the oil leak. If they were working good before ,they will work good again.

    The 205 isn't hard at all. It's messy (the worst part of the rebuild for me was cleaning the thing, followed by the burnt cat pee smell sticking around my garage for months after). I never built a 465, but it can't be that hard. My NV4500 wasn't too hard to disassemble/reassemble.

    Thanks for the info, I think I am going to try the rebuild myself. Where is a good source for rebuild kits?

    I got my rebuild kit for the NP205 from National drivetrain.
